DEPARTMENT OF THE INTERIOR
Fish and Wildlife Service
50 CFR Part 17
Endangered and Threatened Wildlife and Plants; Status of the Rio
Grande Cutthroat Trout
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Status review; reopening of public comment period.
-----------------------------------------------------------------------
SUMMARY: We, the U.S. Fish and Wildlife Service (Service), announce the
reopening of the public comment period on our review of the Rio Grande
cutthroat trout (Oncorhynchus clarki virginalis) to determine if
candidate status is warranted. The Endangered Species Act of 1973, as
amended (Act), requires that we identify species of wildlife and plants
that are endangered or threatened, based on the best available
scientific and commercial information. Through the Federal rulemaking
process, we add these species to the List of Endangered and Threatened
Wildlife at 50 CFR 17.11 or the List of Endangered or Threatened Plants
at 50 CFR 17.12. As part of this program, we maintain a list of species
that we regard as candidates for listing. A candidate is one for which
we have on file sufficient information on biological vulnerability and
threats to support a proposal to list as endangered or threatened but
for which preparation and publication of a proposal is precluded by
higher-priority listing actions. During or prior to April of 2008, we
will make a determination concerning the results of the status review
for the Rio Grande cutthroat trout and, shortly thereafter, we will
publish this determination in the Federal Register.
Comments previously submitted on the status of the Rio Grande
cutthroat trout need not be resubmitted as they have been incorporated
into the public record and will be fully considered in preparation of
the final revised status review.
DATES: We will accept comments and information from all interested
parties for our use in the status review and in preparing a revised
finding until September 17, 2007.
ADDRESSES: If you wish to comment, you may submit your comments and
materials by any of the following methods:
1. You may mail or hand-deliver your written comments and
information to Wally ``J'' Murphy, Field Supervisor, U.S. Fish and
Wildlife Service, New Mexico Ecological Services Field Office, 2105
Osuna NE., Albuquerque, NM 87113.
2. You may fax your comments to Wally ``J'' Murphy, Field
Supervisor, New Mexico Ecological Services Field Office, at (505) 346-
2542.
3. You may send comments by electronic mail (e-mail) to
R2FWE_AL@fws.gov.
4. You may go to the Federal eRulemaking Portal: http://www.regulations.gov.
Follow the instructions for submitting comments.
Comments and materials received, as well as supporting
documentation used in the preparation of the candidate status review,
will be available for public inspection, by appointment, during normal
business hours at the New Mexico Ecological Services Field Office, at
the street address above (telephone: (505) 346-2525).
FOR FURTHER INFORMATION CONTACT: Wally ``J'' Murphy, Field Supervisor,

SUPPLEMENTARY INFORMATION:
Background
For background information on the events leading to our notice of
intent to initiate a status review for the Rio Grande cutthroat trout,
refer to our notice published in the Federal Register on May 22, 2007
(72 FR 28664).
Request for Information
On May 22, 2007, we published a notice of intent to initiate a
candidate status review for the Rio Grande cutthroat trout (72 FR
28644). We accepted public comments for inclusion in the status review
for 45 days, ending July 6, 2007. In response to requests from
interested parties, we are reopening the comment period for an
additional 30 days (see DATES) to offer all interested parties an
opportunity to submit data and information for inclusion in our status
review for this species.
Our determination of candidate status for the Rio Grande cutthroat
trout must be based upon the best available scientific and commercial
data, as required under section 4(b)(1)(A) of the Act (16 U.S.C. 1531
et seq.). We request that you submit any information on the Rio Grande
cutthroat trout not previously submitted for our review. We are
particularly interested in any relevant information gathered since June
2002 concerning the following:
[[Page 46031]]
(1) Current population status (e.g., population estimates, age-
structure, trend) for any of the populations of the Rio Grande
cutthroat trout, including methodology used for population estimation
and confidence intervals if available;
(2) Rio Grande cutthroat trout's susceptibility to whirling
disease, and distribution of Rio Grande cutthroat trout infected by
whirling disease in New Mexico and Colorado;
(3) Distribution of Tubifix tubifix (tubificid worms), an
intermediate host of the parasite known to cause whirling disease in
trout, and the susceptibility of these worms to the parasite in the
streams of New Mexico and Colorado;
(4) Genetic classification of any Rio Grande cutthroat trout
population(s);
(5) Condition of occupied habitat;
(6) Restoration projects that have been completed, including
translocation, new barrier construction or barrier repair, habitat
improvement projects, or nonnative trout removal projects;
(7) Results of barrier surveys;
(8) Distribution of nonnative trout or their population size and
structure in streams currently occupied by Rio Grande cutthroat trout;
(9) Status of any of the thirteen ``core'' populations identified
in the 2002 status review (see 67 FR 39936);
(10) Current and future threats to Rio Grande cutthroat trout
populations and remaining habitat areas;
(11) Other regulatory mechanisms that address those threats; and
the success of those mechanisms to date; and
(12) Whether any portion of the range of the species is a
significant portion of the range, and whether there are threats in that
portion sufficient to meet the standards for listing under the Act.
Our candidate status review will take into consideration all
comments and any additional information received, including all
previous comments and information submitted during the 2002 candidate
status review. As such, information provided during the previous status
review does not need to be resubmitted.
If you are submitting e-mail comments, please include ``Attn: Rio
Grande cutthroat trout'' in your e-mail subject header. If you do not
receive a confirmation from the system that we have received your e-
mail, contact us directly by calling our New Mexico Ecological Services
Field Office at (505) 346-2525. Please note that comments must be
received by the date specified in the DATES section in order to be
considered and that the e-mail address (R2FWE_AL@fws.gov) will be
unavailable at the termination of the public comment period.
Before including your address, phone number, e-mail address, or
other personal identifying information in your comment, you should be
aware that your entire comment--including your personal identifying
information--may be made publicly available at any time. While you can
ask us in your comment to withhold your personal identifying
information from public review, we cannot guarantee that we will be
able to do so.
